How does he smell?

While a majority of dogs have black noses, not all do. The noses of dogs such as vizslas and weimaraners match their coat colours – red and silver, respectively – and it is not unusual for puppies of any breed to start out with pink noses that then darken as the animal matures.

Dogs have most likely developed black noses as a protection against sunburn. While the rest of the dog’s body is protected by fur, light-coloured noses are exposed to the full force of the sun’s rays.
